The Quang Tan Enterprise in Chau Thanh district's An Hiep commune, which has been making the two products for 65 years, said besides selling domestically, it also exports to other countries.

This year it has also made new kinds of sausages from Chinese-style fresh pork and dried shrimp. Delta villages that produce specialty foods now also work at night to meet the massive Tet orders.

In Dong Thap province's Lai Vung district, many households are increasing their production of Lai Vung fermented pork rolls to meet orders.

La Ngoc Thang, owner of a production establishment called Nem Ut Tham in the district's Long Hau commune, said, "My village is entering the peak period of making fermented pork rolls for Tet. Sales of Lai Vung fermented pork rolls now are three or four times that of normal days."
